CONVOLUTIONS OF MEROMORPHIC UNIVALENT FUNCTIONS WITH POSITIVE COEFFICIENTSB.A. UralegaddiDepartment of Mathematics, Karnatak University, Dharwad 580003, IndiaAbstract: Let $f(z)=1/z+\s{a_n}$, $a_n\ge 0$ and $g(z)=1/z+\s{b_n}$, $b_n\ge 0$. We investigate certain properties of the convolution $1/z+\s{a_nb_n}$ where $f(z)$ and $g(z)$ are meromorphically starlike. Keywords: Meromorphic univalent functions, Starlike of order $\alpha$, convolution. Classification (MSC2000): 30C45 Full text of the article:
